The Goal: Build a 3-D model of each cityscape challenge. You won't have to worry about building codes or permits, but you will have to use logic to place all sixteen skyscrapers on their correct building pads. Get it right, and you can run for mayor. Make a mistake, and you'll have to call in the demolition team!

The Challenges: The fifty cityscape challenges are divided into two building phases. The rules for Phase One are similar to Sudoku. The rules for Phase Two are harder and require more reasoning. The challenges in each phase start easy and increase in difficulty. If construction comes to a halt, don't panic. The solution to each cityscape is on the back of each challenge card. So what are you waiting for? Grab your hardhat and start building!
